Title: Boot
Inventor: FURUTA YUJI
IPC: F16D3/84
Filed: 2008-09-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a spiral boot having excellent sealing properties to a material to be sealed and hard to be damaged at demolding.  <P>SOLUTION: A bellows 2 of the boot is comprised of a spiral section 3 and a buffer section 4. The buffer section 4 is continued to a small radius section 5, and at the same time the leading edge of the spiral section 3 in the spiral direction is continued to the buffer section 4. Then, the buffer section 4 is configured to have the maximum inner radius not more than the minimum inner radius of the spiral section 3 and the minimum inner radius not less than the maximum inner radius of the small diameter section 5 and is tapered at least in the part on the side of the small diameter section 5. The spiral section 3 and the small diameter section 5 are not directly continued to one another by placing the buffer section 4 between the spiral section 3 and the small diameter section 5. The spiral section 3 reduces a force to the small diameter section 5 when telescopically deformed by tapering at least the part of the buffer section 4 on the small diameter section 5, resulting in the sealing properties of the small diameter section 5 to a target material to be improved. In addition, the buffer section 4 has a smaller diameter than that of the spiral section 3, so the part forming the inner surface of the buffer section 4 in a core 91 does not interfere with the inner surface of the spiral section 3 in demolding. Consequently, the boot can be inhibited from being damaged in demolding.  <P>COPYRIGHT: (C)2010,JPO&INPIT
